Amerika is the biggest gay club in the city. Entrance fee is ARS 100 but it's "canilla libre"on Fridays and Saturdays. It's always packed.
Glam and Palacio/Alsina and Human are smaller - the crowd is a little stuck up though (or at least they try).
Sitges is the most popular pre-dance bar. Most dudes have a drink or two and go straight to Amerika, that is right around the corner. They take away the tables and turn it into a club after 3am.
Contramano is for the 40+ crowd. Also, the LGBT socio-political movement started there in the early 80s.
Don't bother going to Plop/Puerca/Ambar LaFox / Eyeliner unless they're under 25.
Good luck!
